In 2022, the trend of US 10 national debt yield decreased because the interest rate of long-term and short-term national debt was upside down mainly due to the sharp interest rate increase in the United States. The 2-year interest rate of US debt is upside down with the 10-year interest rate. The upside-down interest rate of long-term and short-term government bonds is mainly due to the sharp interest rate increase in the United States. The rapid rise of short-term interest rates has led to a sharp drop in the price of short-term bonds and a sharp rise in the yield. In the long run, inflation will eventually pass, interest rate hikes will stop, crude oil will fall, PPI will fall, and US bond yields will fall, indicating that inflation will enter the downward channel. However, the interest rate hike will not stop for the time being. Some institutions predict that this round of interest rate hike will last until May 2023, when the Federal Reserve will hold a meeting on interest rates, and the market generally expects to raise interest rates by 50 basis points.
